The fentanyl of porn?

Hello all, I've been avoiding cover this topic as it's a sensitive one, something that has questioned my sexuality. I've never before questioned my sexuality before and know for sure I am heterosexual, I hold nothing against those who think otherwise. It seems that porn has corrupted my thinking, whenever involved in multiple days of relapse I seem to escalate to transgender pornography, I also seem to seek this content out when I've abstained from porn for long periods. I call it the fentanyl of pornography and just wanted to relate with those out there that have felt the same urge I did, the urge to seek out a content that you immediately regret seeking out afterwards. The content we seek out when regular heterosexual porn no long satisfies us, what I consider in my life as the overdose of porn. once again I hold nothing against anyone with different sexuality and seem concerned I've (and many on here) have reached this point of seeking out this level of content in order to get that hit of dopamine.
